Obamacare's 10 essential health benefits have given brokers and agents plenty to chew on during the implementation of the Patient Protection and Affordable Care Act. While they are intended to improve care covered under health plans across the nation, essential health benefits have been shown to drive up the cost of some plans — a side effect largely unknown to many new plan purchasers thanks to the law's subsidies — and has led to cases to coverage incongruity.

For example, men are now required to pay for prenatal care. Childless individuals are required to pay for pediatric care. And people who don't take pills have to pay for prescription coverage.

But even with all those covered areas, there's a glaring omission, especially for workers who've been receiving health care benefits for years. PPACA doesn't cover adult dental care, and the omission has garnered sharp criticism from benefits professionals, health care officials and dentists across the nation.
